Peacock v D M Osborne and Co [1907] HCA 6

All challenged claims (1, 2, 5, and 7) were for novel, useful combinations and were valid subject-matter for a patent. The patent was not invalid despite the specification not distinguishing old from new in the combination, and prior publication of claim 7 did not invalidate the claim due to the operation of section 56 of the Patents Act 1890 (Vic.).
